Je conçois un JPanel en utilisant Netbeans Builder.J'ai copié le code source et l'utilise dans cette classe.J'ajoute aussi une méthode principale avec un constructeur. Exécute le fichier, construit avec succès mais Java VM fait ouvre n'importe quel gui. Voici tout le code.Le code source de Gui Builder ne fait pas gui

Vous avez besoin d'un 'JFrame' pour votre classe' Gui'. Je suppose que le développeur gui a commencé à l'interne comme étant notifié comme un haricot. – SomeJavaGuy
Vous voulez dire que je dois construire un JFrame et .add JPanel sur ceci? Je vais l'essayer mais la question est toujours, pourquoi le constructeur ne le fait pas correctement ?? –
